The Paris Agreement of December 2015 established that global temperature should not increase by more than 1.5 °C above pre-industrial levels (temperatures prior to 1850), in order to prevent the Earth from altering its natural self-regulatory systems. Reports from the IPCC (Intergovernmental Panel on Climate Change) estimated that this threshold would be reached between 2030 and 2050 unless current CO₂ emissions were significantly reduced.

For years, environmental policies focused primarily on the prevention of climate change, under the assumption that cutting emissions would be sufficient to contain its impacts. However, by 2023–2024, the average global temperature increase had already reached between 1.2 °C and 1.3 °C above pre-industrial levels, and recent natural phenomena demonstrate that climate change is no longer a future threat, but a present reality. The concern is no longer whether the world will surpass 1.5 °C, but who will be best prepared to adapt to a rapidly changing planet. The emphasis of climate action must shift from prevention to adaptation: how to live, produce, and prosper within an altered environment.

There is an uncomfortable truth. Those who have contributed the least to climate change are the ones who suffer (or will suffer) the most severe consequences. Climate change is not only an environmental issue, but a manifestation of global inequality. In Mexico, this climatic inequality is particularly visible. Rural and Indigenous communities, heavily dependent on ecosystems, face droughts, soil degradation, and erratic rainfall. Yet their carbon footprint is minimal. Paradoxically, those who live closest to nature are the most affected by a global productive system they cannot control, and which is largely driven by cities and large corporations (which are also better positioned to adapt to climate impacts).

Climate justice demands recognition of the rural population not as passive victims, but as guardians of the land. People who live day-to-day, without access to water, credit, land, or crop insurance, cannot prioritize environmental sustainability or prepare for a difficult future when their most urgent concern is simply surviving the present. In other words, social justice is a prerequisite for climate justice.

However, the climate will not wait for us, and this makes the challenge twofold: addressing rural poverty while simultaneously enabling an ecological transition.

Adaptation must be understood as a human right. Access to water, climate-resilient seeds, adequate infrastructure, agricultural insurance, climate information, and technology should not depend on people’s ability to pay. In a country marked by structural inequality, climate justice requires ensuring that every community has the means to face climate change without being left behind. Resilience cannot be a luxury; it must be part of the social contract.

Climate justice is also intergenerational. It is not only about protecting today’s vulnerable populations but about ensuring that future generations inherit a habitable planet. Every decision that delays climate action imposes a massive cost on young people and children who currently have no political voice. In this sense, adaptation is not merely a technical strategy, but a moral obligation toward the future.

Gender adds another layer of inequality. Rural women, who are often responsible for managing water, food, and family care, face disproportionate impacts. In many communities, climate change increases their workload, reduces their access to resources, and deepens poverty.

Climate justice requires democratizing financing so that communities themselves can decide how and where to invest in protecting their livelihoods.

Education and communication represent essential pillars. In many places, the impacts of climate change are felt long before they are understood. Without accessible information, communities cannot anticipate or plan. Thus, climate justice also entails cognitive justice: acknowledging and strengthening local knowledge systems, traditional forecasting, and ancestral agricultural practices that have enabled survival under extreme climates for centuries.

At the national level, climate justice must be translated into policies that integrate redistribution, food sovereignty, and rural resilience. It is not enough to plant trees, recycle, or promote clean energy; the country must ensure food security, provide small producers with access to green credit, training, and fair markets. Adaptation does not happen in laboratories or offices; it happens in furrows, communal lands, and rural communities where every day people decide what to plant and what to eat.

In sum, climate justice redefines the meaning of progress. It is not about saving an abstract planet but about protecting the material conditions of human life with equity. Those who have contributed the least to the problem deserve to be the first to receive support, not the last. Adaptation must be a guaranteed right, not a purchased privilege. Ultimately, climate justice does not ask for compassion; it demands coherence.
